CUTTIN APPARATUS,

application mea .nine 2o, 191s. serial in. 104,777.

State of Wisconsin, have invented newand useful Improvements in Cutting'Apparatus,

of whichthe' followingis a speciicationQv i '.lhis inventionrelates to alawn mower and the primary` object of the invention is tov provide a cutting device of thisV characterfv wherein a" cutter bar mounted for oscillatory movement below and to one side of the axis of the cutting reel has the blade thereon Fig. 1.

yieldably yet firmly `pressed against a cutting edge of the bladesof the cutting reel during the passage of the blades on the cutting reel over the blade on the cutter bar.

Another object of the invention is to provide a lawn mower in which rings constituting a part of the reel khave formed thereon cam faces, arranged betweenthe blades of the reel and adapted durin the rotation of the reel to engage the blade on the cutter ba'r and oscillate the cutter bar to insure the blades on the cutting reel assing thereon.

W'ith these and other o jectsin view, the

invention resides in the novel combination and arrangement of parts, which will be hereinafter described and particularly pointed out in the claims.

The preferred embodiment of the invention has been illustrated in the accompanying drawings, although -no restriction is necessarily made to the precise details-of construction therein shown, as changes, alterations, and modifications, within -the scope of the claims may be resorted to when desired. i

Like characters of reference denote corre spending parts throughout the several views in the drawings, in which:

mechanism for holding the blade'on the cutthenumeralfl designates the `frame of the lawnmower which comprises spaced plates 2i ter ba'r in the path of movement of the blades on the, cutting reel.

Referring now. to the drawings in detail,j

havingvarms 3 terminating in extensions 4 with which is lconnected a ground roller 5, said plates 2'having connected therewith the A' reel vshaft 7 extends transversely between-the plates 2 andhas its ends extended beyond the ,same in order that the reel shaft may be rotated by ground wheels 8 suitably connected with the plates 2 for this purpose.

Rings 9 are tired; to the shaft 7 in spaced relation and have connected therewith blades 10 (Eo-acting with the. rings in constituting the cutting reel of the lawn mower. i The outer peripheral surfaces of each ring 9 is recessed as at 11, to provide the rings with cam-faces 12 arranged between the blades 10 for a purpose which will hereinafter appear. I

y A bar 13 extends transversely of the frame' 1 below-the axls of the cutting reel and to one side thereof and is provided at its ends with heads 14 in which are formed slots 15, receiving 'therein ribs 16- on the arms 3. Said bar' is detachably connected with the arms vby fastening elements 17 which are passed through suitable openings inthe arms and extend within the 'heads 14.

v The bar 13 has ormedon the sidev thereof opposite the 'cutting reel a central enlargement`18` from which extends la stud 19 terminating at its 'outer-end ina ball-shaped head2@ A 'cutter bar 21l extending transversely of the mower frame between the, barlB and the cutting reel has formed pon one side thereof between its ends ,an ext nsion'22, the upper face of the extension is recessed as as 23,

with the bottom wall of the recess provided with a depression 24 communicatingvwith a flared passage 25 opening out through the iront-wallet the extension 22 and receivting therein the stud 19, the head 20 of which is arranged in the depression 24.- and retained therein by a plate 26 disposed in the recess 23 and secured to the extension 22 in any suitable manner.' l

The side of the cutter bar 21 which has formed thereon the extension 22 is provided at each end with a pair of ears 27 with each pair of ears receiving therebetween a roller 28 having its peripheral face hearing against a head 14 on the bai' 13, 'said rollers serving' as antiiriction devices` The opposite side of the -cuttel` bar is provided at each end with an arin having formed therein at one end an. opening 30.

The bottom face .of the cutter hat 2l i recessed longitudinally for the greater pon tion of its length to receive a portion of the cutting` blade 3l, the cutting edge of which extends slightly beyond the lree ende of the arms 29 to engage 'the cutting edge on the blades 'of the reel during the rotation of the saine, said blade being' secured to the oar 2l in any suitable inannern y Extending laterally from eachr arm to oVer-liethe arm Q9 on the cutter bar adjacent thereto is a lug 32 having formed therein an opening 33.

In order that the cutting blade 3l may "no held yielda'oly yet firmly engaged with the blades on the cutting rcel, as the .blades on the reel pass over the blade on the cutter bar, .rods 554@ are passed through the opeziiings in the lugsI 32 and arms 29 on the cutter can Each rod has at one end a ball shaped 35 held in Contact with an arm 25;) o a coil Y. .l spring 3o encircling the rod 34; and arrangee between the lug 32, and a nut E? adlgustaely mounted on. the rod An end on eaclirod 34k has 'formed 'therein a slot 38 in 'which may loe inserted a sait able instrument such as a screw driver, or the like to hold the rod a amel'. tornino;

5 mei/ement While the not 8l thereon is ad- 3usted to increase or decreet-3e the tension of the s nan 3G eo that 'the s rinvia mai hold 9 *D the Cutter bar in position 'to cau-se the bladethereon to be yieldably yet rinl'y engaged with the blades on the cutting' reel daring their )asser-fc over the cuit har.

t: From the above deem-ioctl iii-inner o cow meeting the cutter bar with the im aree and l'nounting the cutter bar in the cross loer foi oscillatory ino'x'en'xent below the ame of the cutting z' el and to one side ilnere` 7 1t will be seen with reference to the dran mg that a blade and cam face anon ene of the rings on the cutting reel will at all times lic' in engagement with the blade on the cutter liar, so that as the cutting reel rotates the cam faces on the rings Will oscillate the cutter oar to insure the blades on the cutting reel moving thereon and also pei-init the springs 36 to hold the blade on the cutter bar yieldahly, yet rinly engaged with the .blades on the cutting reel during passage over the blade on the cutter bar, wing thus described the invention, what i;ncd new, is:

l. a lawn mower, a reel, a cutter bar 'below the axis of the reel yieldahly held for oscillatory movement, a blade on said cutter liar to engage the blades on the reel, and ringe on said reel having cam faces thereon to engage the blade on the cutter har to oscillatc the bar.

In lawn mower, a reel, a cross bar below the of said reel, a cutter bar yield ahh ,held for oscillator finovement on said cross; ha?, s blade on said cutter bar to en- 'the blades on the reeli rings on said rech cain 'faces on the rings between the blades on the reel to engage the blade on the cutter liar to oscillate the bar, and rollers at the ende of the cutter bar engaging said cross oar.

3., ln a lawn mower, a mower frame, a, reel thereon, rings connected with the blades of the reel recessed to provide cam faces be'- tween said blades, a cross bar below-the axis of the reel connected with the mower frame, central -stud on the side of the cross bar opposite said reel, a cutter bar mounted to oscillate on said stud, rollers on the cutter har contacting with said cross bar, a blade on the cutter bar in the path of movement of the blades on the reel to be engaged by the "aces on said rings to oscillate the cutter bar7 rods slidahly mounted on said frame and engaged with the ends of'tne cutter har, springs; en said rods engaging said mower trame, and nuts adjustably mounted on said rods engaging said springsn ln testimony whereof l. aiiX m signature,
